Bar end mirrors on a BMW R nineT Scrambler KiWAV bar-end mirrors, made in Taiwan

Quick answer: Most BMW standard (perch-mount) mirrors use a 10mm x 1.5 thread, but many popular models — R nineT, S1000R/RR, F800R, and the GS family — have 10mm x 1.25 mounts and need an adapter or BMW-ready bolts (included with many KiWAV mirrors).

2002 Harley Sportster LED Mirrors Wouldn’t Flash: Load Equalizer Fix

KiWAV FLASH chrome LED turn-signal mirror for Harley-Davidson Historical KiWAV product photo of the FLASH chrome LED turn-signal mirror discussed in this case. This is not the customer’s 2002 Sportster.

At a glance: This article is based on an anonymized 12-message KiWAV customer-support case from 2016. After installing KiWAV FLASH OVAL chrome LED turn-signal mirrors on a 2002 Harley-Davidson Sportster, the rider found that the mirror lights illuminated but stayed on instead of flashing. An initial flasher-related parts attempt did not produce a working setup. The rider later installed a plug-and-play NAMZ LE-03-A load equalizer and confirmed on 15 June 2016 that the signals were working correctly. This was a steady-light, no-flash case—not hyperflash—and the result should not be treated as a universal fix for every Harley-Davidson electrical system.

Why the difference?...

Best Motorcycle Bar-End Mirrors in 2026: Picks by Bike Type

bob-heavy-weight-bar-end-mirrors-classic-naked-motorcycle

The best motorcycle bar-end mirror for most riders is a heavy-weight model with a CNC-machined aluminum arm — the added mass at the bar's end damps vibration exactly where it starts, giving you a clearer image than any stock mirror position can. For naked bikes and cafe racers, a minimal round or teardrop design keeps the lines clean; for Ha...
